using ammonia and caustic ammonia induces negligible amounts of n2o, whereas relatively high amounts could be measured when injecting urea directly into the boilers.
l’utilisation de l’ammoniac et de l’ammoniac caustique produit des quantités négligeables de n2o tandis que des quantités relativement élevées peuvent être mesurées lors de l’injection directe d’urée dans les chaudières.

here, the lower burners are operated under fuel-rich conditions, whereas the upper burners are not in use, injecting only air.
dans ce cas, les brûleurs inférieurs seront alimentés par des combustibles riches tandis que les brûleurs supérieurs ne seront pas utilisés en injectant uniquement de l'air.

this air-staging is realised by injecting 30 to 40 % of the combustion air, via nozzles, directly into each elementary flame.
cet étagement d’air est réalisé en injectant 30 à 40 % de l’air de combustion directement dans chaque flamme élémentaire via les buses.

by injecting a portion of the flue-gas into the combustion zone or combustion air supply, both flame temperatures and oxygen concentrations are lowered enabling a reduction of nox formation.
en injectant une portion du gaz de combustion dans la zone de combustion ou dans l’approvisionnement en air de combustion, les températures de flamme et les concentrations en oxygène diminuent et permettent de réduire la formation des nox.
